REINFORCEMENT STRUCTURE AND REINFORCEMENT METHOD

To easily suppress the influence of welding on the surroundings and improve the strength of reinforcement.SOLUTION: The reinforcement structure includes a steel material, a bar material whose tip is welded to the steel material, a plate material attached with a welding space between the steel material and itself, and a metal ferrule fixed to the plate material and arranged in the welding space. The plate material has an insertion hole with a diameter wider than that of the bar member. The metal ferrule has a metal ferrule hole communicating with the insertion hole and having a diameter equal to or larger than that of the insertion hole. The bar material is inserted through the metal ferrule hole and the insertion hole. A gap between the bar material and the metal ferrule hole and a gap between the bar material and the insertion hole are filled with weld metal.SELECTED DRAWING: Figure 2 【課題】溶接による周囲への影響を簡易に抑制するとともに補強の強度の向上を図る。【解決手段】鋼材と、前記鋼材に先端が溶接されている棒材と、前記鋼材との間に溶接空間を有して添設される板材と、前記板材に固定されて前記溶接空間に配置される金属フェルールと、を備え、前記板材は、前記棒材よりも広径の挿通孔を有し、前記金属フェルールは、前記挿通孔に連通するとともに前記挿通孔の径以上の金属フェルール孔を有し、前記棒材は、前記金属フェルール孔及び前記挿通孔に挿通されており、前記棒材と前記金属フェルール孔との間隙、及び、前記棒材と前記挿通孔との間隙に、溶接金属が充填されている。【選択図】図２
